5/16-24 × 2" براغي رأس كباس سداسية | محرك سداسي | كرة نايلون | خيط جزئي | فولاذ سبائك مؤكسد حراري أسود (100 / عبوة)

I needed some extra-strong fasteners for a jig I’m building, and these 2-inch screws with the nylon pellet are holding tight without stripping. The black oxide finish feels sturdy and resist rust, which is exactly what I was hoping for.

The hex socket drive on these screws grabbed my Allen key perfectly without any wobble, and the black oxide finish looks clean on my jig build. For precision assemblies, the nylon pellet locking feature is a nice touch I didn't expect at this price point.

I'd been wasting time on inferior fasteners that kept stripping, but these socket cap screws have hex broaching that's dead-on accurate. The nylon pellet locking feature is a lifesaver for vibration-prone jig setups I'm building.
